Thank you joining the Flink community and contributing.
Considering this specific change: I would like to _not_ merge this change.
There was nothing wrong with the original code - this is a cosmetic change
that does not actually change anything significant. I personally would like to
encourage not doing such changes, because a project can easily get into a
situation where committers spend a significant amount of time formatting code
and style back and forth rather than working on issues for noticeable
improvements.
I would encourage you to look at the "how to contribute" page, which
describes how to find interesting issues for new contributions.
